Vehicle Detection with OpenCV using Contours + Background Subtraction

Vehicle Detection with OpenCV using Contours + Background Subtraction

In this video we will explore how you can perform tasks like vehicle detection using a simple but yet an effective approach of background-foreground subtraction. You will be learning about using background-foreground subtraction along with contour detection in OpenCV and how you tune different parameters to achieve better results.

Contour Detection 101: Contour Analysis (Pt:3)

In the third part of this series, we will be learning about analyzing contours. This is really important because by doing contour analysis you can actually recognize the object being detected and differentiate one contour from another. We will also explore how you can identify different properties of contours to retrieve useful information. Once you start analyzing the contours, you can do all sorts of cool things with them. The application below that I made, uses contour analysis to detect the shapes being drawn!

Contour Detection 101: Contour Manipulation (Pt:2)

In part two of the series, the contour manipulation techniques we are going to learn will enable us to perform some important tasks such as extracting the largest contour in an image, sorting contours in terms of size, extracting bounding box regions of a targeted contour, etc. These techniques also form the building blocks for building robust classical vision applications.
